This guide will break down the formula for calculating cost per mile and provide a detailed 4-step calculation process.  

Understanding the Cost per Mile Formula:

Cost per mile is an important metric which measures the expense of operating a vehicle for each mile driven. The figure is especially important for delivery businesses, rideshare drivers or anyone who relies on a vehicle for their source of income.  

Should we emphasize more on why does cost per mile matter? Because it allows you to: 

  • Track and manage your transportation expenses 
  • Identify areas where you can cut costs 
  • Make data driven decisions about vehicle use and its maintenance 

Formula Breakdown

Cost per Mile = Total Costs / Total Miles Driven

This formula is simple but powerful. By dividing your total costs by the total miles driven, you get a clear picture of your expenses on a per-mile basis. 

Let’s check out the 4-Step Cost per Mile Calculation

Step 1: Determine Your Variable Costs 

Explanation: Variable costs can change, based on your vehicle usage. It is as simple as that. These costs are: 

  • Fuel: The more your vehicle moves, the more fuel you need.  
  • Maintenance and Repairs: Regular maintenance servicing and unexpected repairs.  
  • Tolls and Parking: Fees which vary according to your driving routes and habits.  

When you spend ₹5000 on fuel, ₹2000 on monthly maintenance and ₹1000 on tolls – your variable costs for the month are ₹8000.  

Step 2: Check How Many Miles You Drove 

Only by tracking your mileage will you know your actual miles for a specific period. Here are some ways for tracking your mileage:  

  • Odometer Readings: The odometer in your vehicle shows the mileage, just check the odometer at the start and at the end of your tracking.  
  • Mileage Tracking Apps: Apps like MileIQ or Google Maps can automatically log your miles. Apps like Mile MileIQ or Google maps, these can automatically log your miles. Smart work beats manual – for sure.  

Tools: If your odometer reads 10,000 KM at the start, and 15000 KM at the end of the month – you have driven 5000 KM. Using an app or simple notes, will do the trick here.  

Step 3: Calculate Your Total Costs 

There are two main types of costs to consider in the cost per mile calculation: 

  • Fixed Costs: Consistent costs, which do not vary as per your driving schedules. They include:
    • Insurance: ₹3000 per month (e.g.) 
    • Depreciation: The reduction in your vehicle’s value over the time – ₹2000 (e.g.) 
  • Variable Costs: As discussed earlier, they change according to your usage ratio. From our example, ₹8000 per month. 

Adding fixed costs (₹3000 + ₹2000) and variable costs (₹8000), the total hole in your pocket is worth ₹13000.  

Step 4: Calculate Your Cost per Mile 

Putting It All Together: Combine your total costs and add the mileage – which gives you your cost per mile.  

Cost per Mile = Total Expenses –  ₹13000 / Total distance – 5000 KM = ₹2.60 

This means that it will cost you ₹2.60 for every kilometer driven. This figure can be made more relatable with this example: everytime you drive from Delhi to Gurgaon which is 30 KM – it costs you ₹78 in operating expenses alone.

This is common sense, but as we know – common sense isn’t too common. How to reduce your mileage? Let’s see some important tips:
